Stream Data Centers Breaks Ground on $400M Campus in San Antonio

The property could encompass as much as 1.5 million square feet at full build-out.

Stream Data Centers has broken ground on its third San Antonio project. At full build-out, this data center campus will have up to five AI-ready buildings and 1.5 million square feet of space supporting up to 200 MW of IT capacity. The first 300,000-square-foot building is slated to be ready for occupancy in the second quarter of 2025.

Configured to meet the increasing needs of hyperscalers in Texas and beyond, the $400 million project rises on 135 acres at the intersection of West Military Drive and Loop 1604. Each building in the San Antonio III campus is set to feature up to 40 MW and a proprietary design to serve customers’ near-term cloud and artificial intelligence infrastructure needs.

The design builds on Stream’s environmental commitment and also makes the AI-ready facilities even more efficient as customers move to liquid-cooled high density AI workloads. However, the data halls will be designed to accommodate both air and direct liquid-cooled IT infrastructure.

The new data center campus will also comprise an onsite 334 MW CPS Energy substation with access to important data center hubs in nearby Westover Hills, Texas, as well as in Texas Research Park. The substation will have a 2N configuration.

Other key features include:

  • 120 MW of IT capacity available for new tenant deployments
  • Use of closed loop chillers, resulting in minimal water use
  • Secure campus configuration to support tenant requirements for buildings with individual secured perimeters or for the combination of lots on the parcel.

San Antonio expansion

The new campus will be located less than 5 miles from Stream’s San Antonio II data center complex which opened in 2014 at 9550 Westover Hills Blvd. The company entered the San Antonio market in July 2008, when it acquired a 150,000-square-foot, 30 MW facility at 5200 Rogers Road that was sold to a Fortune 10 company in 2011.

Stream Data Centers is the technical real estate affiliate of Stream Realty Partners. Since its 1999 inception, it has acquired, developed and managed more than 27 data center projects in major markets across the country including Dallas-Fort Worth, Houston, Phoenix and Chicago.
